[angularjs] ng-repeat :filter by single field

I have an array of products that I'm repeating over using ng-repeat and am using

<div ng-repeat="product in products | filter:by_colour"> 

to filter these products by colour. The filter is working but if the product name / description etc contains the colour then the product remains after the filter is applied.

How do I set the filter to only apply to the colour field of my array rather than every field?

You must use filter:{color_name:by_colour} instead of

filter:by_colour

If you want to match with a single property of an object, then write that property instead of object, otherwise some other property will get match.

Search by color:

<input type="text" ng-model="searchinput">
<div ng-repeat="product in products | filter:{color:searchinput}">

you can do an inner nest too.

filter:{prop1:{innerprop1:searchinput}}

Specify the property in filter, of object on which you want to apply filter:

//Suppose Object
var users = [{
  "firstname": "XYZ",
  "lastname": "ABC",
  "Address": "HOUSE NO-1, Example Street, Example Town"
},
{
  "firstname": "QWE",
  "lastname": "YUIKJH",
  "Address": "HOUSE NO-11, Example Street1, Example Town1"
}]

But you want to apply filter only on firstname

<input type = "text" ng-model = "first_name_model"/>
<div ng-repeat="user in users| filter:{ firstname: first_name_model}">

Be careful with angular filter. If you want select specific value in field, you can't use filter.

Example:

javascript

app.controller('FooCtrl', function($scope) {
   $scope.products = [
       { id: 1, name: 'test', color: 'lightblue' },
       { id: 2, name: 'bob', color: 'blue' }
       /*... etc... */
   ];
});

html

<div ng-repeat="product in products | filter: { color: 'blue' }"> 

This will select both, because use something like substr
That means you want select product where "color" contains string "blue" and not where "color" is "blue".

If you want to filter on a grandchild (or deeper) of the given object, you can continue to build out your object hierarchy. For example, if you want to filter on 'thing.properties.title', you can do the following:

<div ng-repeat="thing in things | filter: { properties: { title: title_filter } }">

You can also filter on multiple properties of an object just by adding them to your filter object:

<div ng-repeat="thing in things | filter: { properties: { title: title_filter, id: id_filter } }">

Specify the property (i.e. colour) where you want the filter to be applied:

<div ng-repeat="product in products | filter:{ colour: by_colour }">

If you were to do the following:

<li class="active-item" ng-repeat="item in mc.pageData.items | filter: { itemTypeId: 2, itemStatus: 1 } | orderBy : 'listIndex'"
                id="{{item.id}}">
    <span class="item-title">{{preference.itemTitle}}</span>
</li>

...you would not only get items of itemTypeId 2 and itemStatus 1, but you would also get items with itemType 20, 22, 202, 123 and itemStatus 10, 11, 101, 123. This is because the filter: {...} syntax works like a string contains query.

However, if you were to add the : true condition, it would do filter by exact match:

<li class="active-item" ng-repeat="item in mc.pageData.items | filter: { itemTypeId: 2, itemStatus: 1 } : true | orderBy : 'listIndex'"
                id="{{item.id}}">
    <span class="item-title">{{preference.itemTitle}}</span>
</li>

Best way to do this is to use a function:

html

<div ng-repeat="product in products | filter: myFilter">

javascript

$scope.myFilter = function (item) { 
    return item === 'red' || item === 'blue'; 
};

Alternatively, you can use ngHide or ngShow to dynamically show and hide elements based on a certain criteria.

You can filter by an object with a property matching the objects you have to filter on it:

app.controller('FooCtrl', function($scope) {
   $scope.products = [
       { id: 1, name: 'test', color: 'red' },
       { id: 2, name: 'bob', color: 'blue' }
       /*... etc... */
   ];
});

<div ng-repeat="product in products | filter: { color: 'red' }"> 

This can of course be passed in by variable, as Mark Rajcok suggested.

If you want filter for one field:

label>Any: <input ng-model="search.color"></label> <br>
<tr ng-repeat="friendObj in friends | filter:search:strict">

If you want filter for all field:

 label>Any: <input ng-model="search.$"></label> <br>
 <tr ng-repeat="friendObj in friends | filter:search:strict">

and https://docs.angularjs.org/api/ng/filter/filter good for you

my way is this

subjcts is

[{"id":"1","title":"GFATM"},{"id":"2","title":"Court Case"},{"id":"3","title":"Renewal\/Validity"},{"id":"4","title":"Change of Details"},{"id":"5","title":"Student Query"},{"id":"6","title":"Complains"}]

sub is a Input field or whatever you like

Displaying like this

<div ng-if="x.id === sub" ng-repeat=" x in subjcts">{{x.title}}</div>
